Abstract: 1,209,983. Composite casting processes. E. KEMMING. 20 Sept., 1968 [22 Dec., 1967], No. 44909/68. Heading B3F. [Also in Division C7]  Welding rods are prepared by stirring a solid particulate carbide into a melt and drawing off the melt into heat resistant vacuum tubes. The melt used contains in wt. per cent. The preferred carbide is tungsten carbide which may be added to comprise up to 40% but, preferably, at least 7% by weight of the mixture based upon the total weight of the mixture. The tungsten carbide used may be made by alloying the elements (W 2 C) or by a sintering process (WC) and preferably contains Mo, Ti, Ta and/or Nb carbides in the form of mixed crystals to increase its stability in the melt. If sintered tungsten carbide is used this should be added to the melt before the chromium. A melt containing 70% wt. Co and 30% wt. Cr (the Cr containing 2À2% wt. C) was prepared and pulverized W 2 C of a grain size from 2 to 5 microns was introduced into the melt while the melt was stirred inductively. The resulting suspension at 1400‹ to 1750‹ C. was drawn off into quartz tubes by a vacuum and allowed to solidify.

Title: Semiconductor charge storage devices
IPC: H01L29/423
Filed: 1971-09-30
Abstract: 1325099 Semi-conductor devices WESTERN ELECTRIC CO Inc 30 Sept 1971 [5 Oct 1970] 45487/71 Heading H1K A charge storage device comprises, in a single semi-conductor body, a plurality of elements each having a source and a drain and first and second gate electrodes disposed between them, each drain being common to a plurality of sources and each second gate being common to a plurality of sources or connected to the second gate associated with another source. The gates are so disposed that both have to be similarly poled to provide a current path between source and drain. Although in the described arrangements the sources and drains are P-type diffusions in an N-type silicon substrate and insulated gates are used the use of PN or Schottky barrier gates, MOS sources and Schottky barrier drains is also envisaged. The elements may act as photodetectors in an imaging device. In this case with a source floating illumination near it causes it to collectminority carriers which are transferred to the drain by biasing both gates on to give an output indicative of light intensity. When used simply as a memory cell information is fed in by transferring a potential on the drain indicative of a binary 0 or 1 to the source by biasing the gates on. During read-out the drain current is indicative of the stored binary state. A line imaging device is shown in plan in Fig. 2. Sources 11 are floating, first gates 14 connected in groups to one of the outputs of shift register 22, second gates 15 to outputs of shift register 23, and the drain to a load circuit. The elements are scanned by reading pulses applied to gates 14, 15 from the shift registers such that the pulses are coincident on each element in turn. In a modification the elements form an X-Y array, with the drains and the first gates of all elements in a column respectively commoned, as are the second gates of all elements of a row. Read-out of an nÎn array is effected by column and row scan registers each consisting of a pair of shift registers with #n outputs. Output capacitance is minimized by connecting an IGFET in series with each column of elements.

IPC: G03B15/05
Filed: 1967-10-10
Abstract: 1,198,330. Control systems for flash discharge tubes. RICOH K.K. 10 Oct., 1967, No. 46267/67. Heading H2H. [Also in Divisions G2-G3] A control circuit for synchronizing the firing of a flash gun with the opening of the camera shutter includes a variable delay circuit so that the flash can be fired at any predetermined moment during the period in which the shutter is opening and closing. In the circuit shown, when the main switch S1 in the battery line is switched on, capacitors C2 and C3 begin to charge up, during which period a transistor Q2 is on, and a transistor Q3 is off. When the capacitor C3 has charged sufficiently, the base of Q2 becomes more positive, and Q2 switches off, causing Q3 to switch on, and a trigger pulse is generated through a transformer T2 to the control electrode Z of the flash tube F. The tube does not fire because capacitor C2 (which has a larger time constant than C3) is not yet fully charged. When the flash tube is ready for operation a neon tube Ne lights up, and the shutter release, which also closes the switch S2, is actuated. This discharges capacitor C3 through a variable resistor VR, and when it has discharged sufficiently, transistor Q2 is switched on, and Q3 off, so a further trigger pulse is applied to electrode Z. Capacitor C2 (which is in circuit with a transformer T1 and a rectifier diode D to provide a high D.C. voltage for the tube F) is now fully charged, and the tube fires. By adjusting the variable resistor VR, the time delay between the instant of shutter release and the firing of the flash can be varied. Thus the period of maximum intensity of the flash can be arranged to occur at any given instant between the moment the shutter begins to open and the moment when it is completely closed again. The variable resistor may be coupled to the distance setting ring of the camera.

Abstract: 1450183 Zero-suppression circuits HITACHI Ltd 4 Oct 1973 [4 Oct 1972] 46393/73 Heading G4H A zero suppression circuit includes an N-stage register arranged to store signals indicative of whether respective digits of an n-digit. decimal number are zero and the position of a decimal point; and upper and lower insignificant zeros detector circuits each receiving the outputs of all stages of the register. As disclosed; the register is a shift register with 8 stages each storing a bit which is 1 if the corresponding position of an 8-digit BCD number is non-zero or contains a decimal point. Each gate of a set of 8 OR gates in the upper insignificant zeros detector circuit receives the outputs of the corresponding and all higher stages of the register, and each gate of a set of 8 OR gates in the lower insignificant zeros detector circuit receives the outputs of the corresponding and all lower stages of the register. The OR gates which thus receive only one input may be replaced by direct connections. Corresponding gates in the two sets are ANDed together, to control display or printing of the digits of the BCD number, either directly or via a serializing shift register. The first-mentioned register is fed via an OR gate from a decimal point register and from means to recognize a non-zero decimal digit in a BCD number register. This recognition means is a flip-flop reset once per decimal digit time, or a 4 input OR gate.
